I HEADLIGHT.

To all whom it may concern Be it known that I,,RoBnRr H. KAISER, a

citizen of the United States, residing at Chicago, in the county ofCook, State of Illinois, have invented certain new and usefulImprovements in Headlights; and I do hereby declare the following to afull, clear, and exact description of the 1nvent1on, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to automobile headlights.

The object of the invention 1s to provide a headlight for automobileswhlch, whlle diffusing a bright light over a large area, avoids anyglare which will blind thedrivers of approaching cars. The 1nvent1on 1sbased upon the principle of indirect llghting, but utilizes practicallythe same amount of reflecting or radiating surface as is at presentcustomary in automobile headlights.

A further object of the invention is to provide such a structure which1s not only capable of inexpensive embodiment into a new headlight, butcan also be manufactured as an attachment for headlights already in use.

With the above objects in view, and such others relating to the detailsof construction, as may hereinafter appear, my 1nvent1on WillIlOW' befull set forth and described, reference being ad to the accompanyingdrawings.

In the drawin s:- Figure l is a rent elevation of a lamp, Fig. 2 is alongitudinal section therethrough,

, Fig. 3 is a rear elevation of a lamp sup- P Fig. 4 is an enlargedtransverse section therethrough,

Fig. 5 is a perspective view of an annular 10b6, i g Fig. 6 is a detailfragmentary elevation showing the manner in which the lamp support andlamp casing are connected,

Fig. 7 is a section through a modlfied form of the invention, and

Fig. 8 is a fragmentary detailview thereof. I

Referring more particularly to the drawings, 1 represents ashell casingformed in accordance with the accepted forms of automobile headlights,said casing having the side brackets 2 into which the standards ofdevice is constructed as Speciflcation of Letters Patent; Patented May13, 1919. Application filed November 27, 1917. Serial No. 204,208.

a lamp support may be inserted. Also, the

position. The flanged ring 3 also provides a stop for an annular base 6which carries n plurality of lam sockets 7 within which the lamps 8 areinserted. The annulus or base 6 is preferably ahollow metal structureinto one of whose faces the sockets 7 are recessed, so that the lamps 8project beyond the face of the annulus only to the extent of the bulbportions thereof. The several sockets 7, wh1ch are arranged in numberaccording to the power of the searchlight to be constructed, are wiredtogether at the rear of the annulus, the connecting wires being thencollected into a cord" 9 which may be incased in the conduit 3. Theannulus 6 is hinged to the rim of the casing 1, preferably at the lowerside of the latterso that the annulus may be swung downwardly and outitsclosed position.

8, the latter are covered with a circular globe 11 whose edges conformto the innerand outer edges of the annulus 6, and is held thereonbymeans of clips 12 carried by the annulus. The globe 11 isalso made oftranslucent material, such as milk white glass. The annulus or base 6 iscovered, in its closed position, by means of a closure plate 13 ofsuitable design, the closure 13 having a lens inserted into an aperture14 therein and being hinged to the shell 1 and being mounted upon theshell in hinged relation after the manner of the usual an automobileheadlight.

In the form shown in Figs. 7 and 8, the an. attachment for In itsessential headlights already in use.

base or annulus particulars relatingto the lens frame of" provides ameans for locking properly diffuse ,the light 6, the structure is thesame as that described .inthe first form, but the shell is in the formof a comparatively wide collar which ma be slipped over the body orshell of .an ordinary headlight, from the rear thereof, the

I flector, an annular lamp edge and of a suitable distance the annulusor base 6 gvith its lamps and globe, is inserted into the front end ofthe collar until it rests against the ring 5, after which the.

cover or closure 13 is placed in position. The lights, when lighted,throw their rays against the reflector ofthe headlight, from whence theyare transmitted in diffused relation on the roadway.

It will be apparent from the foregoing description that the headlightwhich I have devised constitutes a very simple and inexpensiveconstruction which will throw a -highly diffused light upon a roadwaywith no glare or other dangerous or in]urious characteristics.Furthermore, the device is capable of instalment upon automobile lampsalready in use, as well as in new lamps, the essential feature of thestructure consisting'in the proper arrangement of the annulus 6 with itsplurality of lamps, within the shell so that the light will betransmitted first to the rear in diffused relation, and then reflectedforwardly onto the road.

What I claim as m invention is 1. An electric hea light comprising acasing having an annular mouth, an attaching ring in the mouth of thecasing having its peripheral portion engaged within the periphery ofsaid casing, the inner portion of the ring being inwardly offset,aboWl-shaped reflector having its mouth portion disposed,

about and secured on the inwardly offset portion of the rings, anannular lamp base seated in the outer portion of the ring and lampscarried by the inner side of said base.

2.. Anelectric headlight comprisin a rebase mem er secured at the mouthportion of the reflector and having its inner diameter substantiallyless than the diameter of said mouth portion 1,aos,saa

member shields the lamps from view at the front of the headlight, and atranslucent shield for said lamps comprising an annular body ofchanneled cross-section and having its edge portions secured at the edgeportions of the inner face of the lamp base.

4-. An electric headlight comprising a bowl-shaped shell, a bowl-shapedreflector of translucent light diifusing material disposed within theshell and spaced from the walls thereof, a plurality of lamps disposedwithin the mouth portion of the shell, means for shielding the lampsfrom view at the front of the shell and translucent light'diffusincoverin for said lamps.

. 5. n electric headlight comprising a shell havin an annular mouthportion, a bowl-shape reflector in said mouth portion, an annular lightbase and shield member hingedly connected with the shell and movable tolie within the mouth portion thereof, and a series of lamps mounted onthe inner face of said member.

6. In a lamp of the class described, the combination of an outer-shell,a reflector contained therein, an annular channeled frame piecesecuredto the forward end of the shell, and an annular series of electric lampspositioned Within said channeled frame piece, the latter serving toprevent the rays from said lamps from passing directly through the frontof the lamp casing.

In testimony whereof, I aflix my signature in the presence of twowitnesses.
